Rasmussen: Obama Up By 7

Why? Well, this 7 point lead is the biggest Obama has ever had in Rasmussen’s polling, and Rasmussen’s numbers are the most stable since they poll likely voters and have a bigger sample than Gallup.

Also, let’s not ignore the fact that Obama has been at 51% for the past three days. And for a candidate to be so far ahead this late in the game is extremely important because it’s incredibly hard to change voter’s minds in the last month, as I detailed yesterday.

The details…

Forty-two percent (42%) of voters are certain they will vote for Obama and will not change their mind. Thirty-eight percent (38%) say the same about McCain. Fifteen percent (15%) express a preference for one of the candidates but could still change their mind.

Nationally, Obama is viewed favorably by 58% of voters, McCain by 52%. This is McCainâ€™s lowest his favorable rating since June 15.

Obama leads 63% to 32% among voters who name the economy as the top voting issue. McCain lead 74% to 24% among those who say that national security is the highest priority. Fifty percent (50%) of voters say the economy is most important while just 19% see national security that way.
